The purpose of this study was to investigate the dietary habits and altered food preferences of stroke patients. One hundred and forty-six outpatients, who had experienced their first-ever stroke and were admitted to Asan Medical Center between July and December 2000, were studied. Using interviews, we assessed the altered food preferences, food consumption frequency, and other factors influencing the food preferences and food consumption frequency of the subjects. These results were analyzed with 2 t-tests, and multiple regression analysis, using the SPSS package program. Preferences for pork, red fish, coffee, bread and stews were higher in male stroke patients than in females. The frequency of consumption of beef, pork, white fish, red fish, egg, garlic, onion, coffee, instant noodles, bread, and culinary vegetables increased in the male stroke patients more than in the females. Food preferences were influenced by income, risk factors, subjective tastes and location of brain ischemic lesions. Food consumption frequency was affected by food preference, income, drugs, alcohol, marital status, sex, and dysgeusia. As a result of multiple regression analysis, the frequency of consumption of white fish, red fish, eggs, soy milk, milk, garlic, onions, coffee, noodles, bread, bean-paste stew, kimchi, culinary vegetables, and greasy foods were the most affected by each food preference. Our results suggest that food consumption frequency may vary with food preference, income, drugs, alcohol, marital status, sex, and dysgeusia, and nutrition education should be formulated to prevent stroke recurrence based on the food preferences, subjective tastes, and risk factors of individual stroke patients.

BACKGROUD/OBJECTIVES: Understanding the factors associated with fish consumption is necessary to determine strategies to improve the fish consumption particularly those high in omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA). The aim of this study was to analyse the correlation between a mother's perspective on fish and actual fish consumption in their children. SUBJECTS/METHODS: Two hundred thirty-one elementary school children grade 3-6 and their mothers in Surakarta were recruited using multi stage random sampling for this study. Data was collected in July and August 2017. A validated questionnaire consisted of 3 topics including knowledge related to the health benefits and organoleptic properties of fish and cooking technique-related attitudes on fish were used to measure the mother's response to the fish properties. A validated food frequency questionnaire and a food picture book of fish specifically designed for the survey were developed and used to assess fish consumption of the children. A χ² test was used to analyse the correlation between the mothers' perspective on fish and their children's fish consumption. RESULTS: The median fish consumption in children was 65 g/d with fried non-oily or lean fish, e.g., milkfish (locally called Bandeng) and catfish (locally called Lele) were consumed more than oily fish as well as processed fish products. Of all children, 31% met the fish consumption recommended by the Environmental Protection Agency-Food and Drug Administration 2017. There was no relationship between a mother's knowledge related to health benefits, organoleptic properties and cooking technique-related attitude toward fish and her child's fish consumption. CONCLUSIONS: The fish consumption of children is not influenced by their mother's perspective on fish. Nutrition education strategies are warranted to improve fish consumption and maintain the optimal benefits by consuming fish, including fish high in n-3 LCPUFA.

The effects of feeding frequency on the growth, food consumption, body composition, and hematological response of the Korean rockfish Sebastes schlegelii were investigated for 77 days at ambient water temperatures (17.2-24.5℃) in a sea cage in Tongyeong, Korea. Three replicate groups of fish were hand-fed to satiation with a commercial diet in one of four different feeding frequency trials (one meal every 2 days, and one, two and three meals per day). At the end of the experiment, the mean weight gain, specific growth rate, and daily feed intake of fish fed one and two meals per day were significantly higher than those of fish fed one meal every 2 days or three meals per day. The feed efficiency of the fish fed three meals per day was significantly lower than that of the fish in the other groups. The glucose concentration of fish fed one meal every 2 days was significantly higher than that of the other groups. We conclude that the optimum feeding frequency for improving the growth of Korean rockfish weighing 100-200 g reared in sea cages is one meal per day under our experimental conditions.

Limited epidemiologic data is available regarding the cardiovascular effects of mercury exposure. The purpose of this study was to determine the relationship between mercury exposure from fish consumption and cardiovascular disease in a nationally representative sample of Korean adults using the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV 2008~2009). Survey logistic regression models accounting for the complex sampling were used to estimate the odds ratios (OR) adjusted for fish consumption frequency, age, education, individual annual income, household annual income, body mass index (BMI), waist circumference (WC), alcohol consumption status, and smoking status. The mean blood mercury level in the population was $5.44{\mu}g/L$. Trends toward increased blood mercury levels were seen for increased education level (P=0.0011), BMI (P<0.0001), WC (P<0.0001), and fish (i.e., anchovy) consumption frequency (P=0.0007). The unadjusted OR for hypertension in the highest blood mercury quartile was 1.450 [95% confidential interval (CI): 1.106~1.901] times higher than that of the lowest quartile. The fish consumption-adjusted OR for hypertension in the highest blood mercury quartile was 1.550 (95% CI: 1.131~2.123) times higher than that of the lowest quartile, and the OR for myocardial infarction or angina in the highest blood mercury quartile was 3.334 (95% CI: 1.338~8.308) times higher than that of the lowest quartile. No associations were observed between blood mercury levels and stroke. These findings suggest that mercury in the blood may be associated with an increased risk of hypertension and myocardial infarction or angina in the general Korean population.

The aim of this study was to investigate the association of CD36, a class B scavenger receptor, rs6969989 polymorphism with the serum lipid profiles in Korean women, together with their modulation by oily fish consumption. Subjects were participants from the Korean Genome Epidemiology Study (KoGES), which was initiated in 2001 as a large-scale. A total of 4,210 women aged 39 to 70 were included in this study. Data were collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. Dietary intake was analyzed using a semi-quantitative food frequency questionnaire. The minor allele frequency for rs6969989 was found in 12% of this population. Homozygotes minor G allele at the rs6868989 exhibited significantly higher high density lipoprotein cholesterol (HDLC) concentrations (P-trend=0.043) and lower fasting glucose (P-trend=0.013) than major allele A carriers. The risk of low HDL-C was significantly lower in homozygotes for the G allele than the A allele carriers (P-trend=0.032). Gene-diet interaction effects between rs6969989 and oily fish intake were significantly associated with the risk of dyslipidemia (P-interaction=0.004). Subjects with homozygotes minor G allele and high oily fish intake generally had a lower risk of dyslipidemia than did those with major allele homozygotes and low oily fish intake. These findings supported that oily fish consumption may modulate the contributions of CD36 rs6969989 on genetic predisposition to the risk of dyslipidemia.

어류는 두뇌발달에 중요한 영양소이기도 하지만 신경독인 메틸수은을 함유하고 있는 것으로 알려져 있다. 메틸수은은 임산부가 임신 중에 태아의 두뇌에 치명적인 손상을 유발하는 것으로 알려져 있다. 따라서 연구자들은 생선소비와 임산부 제대혈 중의 메틸수은 함량을 확인하기 위하여 통영지역 임산부 159명을 대상으로 2010년 10월부터 2011년 3월 사이에 임산부의 생선소비와 제대혈의 수은농도의 관계를 조사하였다. 어류소비 관련자료는 설문조사를 통하여 수집하였고 통계처리는 one way ANOVA 를 이용하였다. 조사에 참여한 임산부의 평균나이는 30.1세이었고 임산부 제대혈의 수은 함량은 0.01-14.80 ppb 범위에 평균 $2.69{\pm}2.50ppb$이었다. 제대혈의 평균 수은함량은 WHO 기준인 5.0 ppb를 초과하지는 않았지만 159명 중 17명(10.7%)이 WHO 기준을 초과하였다. 연령별로는 30세 이상이 0.01-14.8 ppb 범위, 평균 $3.18{\pm}2.74ppb$로 29세 이하에서 0-8.00 ppb 범위, 평균 $2.04{\pm}2.00ppb$ 보다 1.6배 높았으며 유의적 차이가 있었다. 이 연구에서 생선섭취가 제대혈의 수은농도에 영향을 미치는 것으로 나타났다. 1주일에 3회 이상 섭취군이 평균 $4.15{\pm}4.02ppb$로 주 1-2회 섭취군의 $2.63{\pm}2.22ppb$, 먹지 않는 군의 $1.60{\pm}1.44ppb$ 보다 2.6배와 1.6배 각각 높게 나타났으며 적게 먹는 군과 먹지 않는 군과의 사이에는 유의적 차이가 없었고, 많이 섭취하는 군과는 유의적 차이 (p < 0.05)가 있었다. 이상의 결과에서 제대혈의 수은 농도는 생선섭취량과 관련이 있는 것으로 판단되며 가임기 여성이나 임산부에게 생선섭취를 제한하는 것이 제대혈의 수은 농도를 낮출 수 있고 향후 있을지도 모를 신생아의 신경발달 장애나 뇌 신경학적 손상을 줄일 수 있는 방법이라고 생각되었다.

In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

Mercury is a chemical pollutant widely present in the environment. Humans are generally exposed to mercury in the form of organic Hg (methylmercury) through the consumption of seafood. Koreans enjoy eating fish therefore blood mercury concentration is usually higher than in developed countries. By investigating blood mercury concentration according to the frequency of seafood consumption and sociodemographic factors, we aimed to identify recent trends in blood mercury concentration in Korean adults. This study was conducted using KoNEHS cycle 4 (2018~2020) from the National Institute Environmental Research Survey. The geometric mean concentration of blood mercury of the subjects was 2.959 (±1.018) ㎍/L, which was significantly higher in men than in women. It was observed that as the frequency of fish and shellfish consumption increased, the blood mercury concentration increased. In adjusted logistic regression, fish consumption was associated with 36.7% increased risk of blood mercury levels [Odds ratio, 1.367; 95% confidence interval (CI), 1.246~1.500], and shellfish consumption was associated with 26.5% increased risk of blood mercury levels [Odds ratio, 1.265; 95% confidence interval (CI), 1.134~1.410]. Blood mercury concentration was also found to increase as the socioeconomic level increased. In conclusion, the geometric mean concentration of blood mercury was increased compared to the one in the 3rd KoNEHS (2015~2017) and seafood consumption and socioeconomic level were still significantly associated with increasing blood mercury concentration in Korea. Therefore, it is necessary to encourage healthy seafood consumption habits and conduct continuous monitoring considering various factors to reduce blood mercury levels.
